Sexual reproduction cycle of basidiomycetes Basidiomycota life cycle Cell cycle of a Dikaryotic basidiomycete Unlike animals and plants which have readily recognizable male and female counterparts, Basidiomycota (except for the Rust ( Pucciniales )) tend to have mutually indistinguishable, compatible haploids which are usually mycelia being ...
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. Anamorph: an asexual reproductive stage (morph), often mold-like.
Ascomycota life cycle and morphology. The phylum Ascomycota, or sac fungus, is characterized by formation of meiotic spores called ascospores enclosed in a special sac called an ascus. The genetic components for sexual reproduction appear to be produced by all members of this group. [6]
Clamp connections are structures unique to the phylum Basidiomycota. Many fungi from this phylum produce spores in basidiocarps (fruiting bodies, or mushrooms), above ground. Though clamp connections are exclusive to this phylum, not all species of Basidiomycota possess these structures.
They are mostly Ustilaginomycetes (phylum Basidiomycota) and comprise seven of the 15 orders of the subphylum. Most described smuts belong to two orders, Ustilaginales and Tilletiales. [1] The smuts are normally grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction. [2]
For example, the ubiquitous and industrially important mold, Aspergillus niger, has no known sexual cycle. Thus Aspergillus niger was considered a form taxon. In contrast, isolates of its close relative, Aspergillus nidulans , revealed it to be the anamorphic stage of a teleomorph (the ascocarp or fruiting body of the sexual reproductive stage ...
A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcefully expelled at full growth. The word basidium literally means "little pedestal". This is the way the ...
The fruitbody is part of the sexual phase of a fungal life cycle, [1] while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a basidiocarp or basidiome, while the fruitbody of an ascomycete is known as an ascocarp.
